Temporal variability in large grazer space use in an experimental landscape
Abstract Land use, climate change, and their interaction each have great potential to affect grazing systems. With anticipated more frequent and extensive future drought, a more complete understanding of the mechanisms that determine large grazer landscape‐level distribution under varying climatic c...

Abstract Land use, climate change, and their interaction each have great potential to affect grazing systems.
